The molecular interactions responsible for hydrogen bonding in $HF$ are:

The correct order of viscosity of the following liquids will be:

Hydrogen bonding is maximum in

What type of intermolecular or intramolecular forces are present in ethylene glycol?

Hydrogen bonding is present in

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Dipole-dipole interactions are the only non-covalent interactions resulting in hydrogen bond formation.
Reason $R$: Fluorine is the most electronegative element and hydrogen bonds in $HF$ are symmetrical.
